[0] https://lists.fosdem.org/pipermail/fosdem/2022q4/003473.html) ----------------------------------------------------------------------- We are excited to announce that the call for proposals is now open for the Virtualization & IaaS devroom at the upcoming FOSDEM 2023, to be hosted on February 4th 2023. This devroom is a collaborative effort, and is organized by dedicated folks from projects such as OpenStack, Xen Project, KubeVirt, QEMU, KVM, and Foreman. We would like to invite all those who are involved in these fields to submit your proposals by December 10th, 2022. Important Dates --------------- Submission deadline: 10th December 2022 Acceptance notifications: 15th December 2022 Final schedule announcement: 20th December 2022 Conference devroom: first half of 4th February 2023 About the Devroom ----------------- The Virtualization & IaaS devroom will feature session topics such as open source hypervisors or virtual machine managers such as Xen Project, KVM, bhyve and VirtualBox as well as Infrastructure-as-a-Service projects such as KubeVirt, Apache CloudStack, OpenStack, QEMU and OpenNebula. This devroom will host presentations that focus on topics of shared interest, such as KVM; libvirt; shared storage; virtualized networking; cloud security; clustering and high availability; interfacing with multiple hypervisors; hyperconverged deployments; and scaling across hundreds or thousands of servers. Presentations in this devroom will be aimed at developers working on these platforms who are looking to collaborate and improve shared infrastructure or solve common problems. We seek topics that encourage dialog between projects and continued work post-FOSDEM. Submit Your Proposal -------------------- All submissions must be made via the Pentabarf event planning site[1]. If you have not used Pentabarf before, you will need to create an account. If you submitted proposals for FOSDEM in previous years, you can use your existing account. After creating the account, select Create Event to start the submission process. Make sure to select Virtualization and IaaS devroom from the Track list. Please fill out all the required fields, and provide a meaningful abstract and description of your proposed session. Submission Guidelines --------------------- We expect more proposals than we can possibly accept, so it is vitally important that you submit your proposal on or before the deadline. Late submissions are unlikely to be considered. All presentation slots are 30 minutes, with 20 minutes planned for presentations, and 10 minutes for Q&A. All presentations will be recorded and made available under Creative Commons licenses. In the Submission notes field, please indicate that you agree that your presentation will be licensed under the CC-By-SA-4.0 or CC-By-4.0 license and that you agree to have your presentation recorded. For example: "If my presentation is accepted for FOSDEM, I hereby agree to license all recordings, slides, and other associated materials under the Creative Commons Attribution Share-Alike 4.0 International License. Sincerely, <NAME>." In the Submission notes field, please also confirm that if your talk is accepted, you will be able to attend FOSDEM and deliver your presentation. We will not consider proposals from prospective speakers who are unsure whether they will be able to secure funds for travel and lodging to attend FOSDEM. (Sadly, we are not able to offer travel funding for prospective speakers.) Submission Guidelines --------------------- Mentored presentations will have 25-minute slots, where 20 minutes will include the presentation and 5 minutes will be reserved for questions. The number of newcomer session slots is limited, so we will probably not be able to accept all applications. You must submit your talk and abstract to apply for the mentoring program, our mentors are volunteering their time and will happily provide feedback but won't write your presentation for you! If you are experiencing problems with Pentabarf, the proposal submission interface, or have other questions, you can email our devroom mailing list[2] and we will try to help you. How to Apply ------------ In addition to agreeing to video recording and confirming that you can attend FOSDEM in case your session is accepted, please write "speaker mentoring program application" in the "Submission notes" field, and list any prior speaking experience or other relevant information for your application. Code of Conduct --------------- Following the release of the updated code of conduct for FOSDEM, we'd like to remind all speakers and attendees that all of the presentations and discussions in our devroom are held under the guidelines set in the CoC and we expect attendees, speakers, and volunteers to follow the CoC at all times. If you submit a proposal and it is accepted, you will be required to confirm that you accept the FOSDEM CoC. If you have any questions about the CoC or wish to have one of the devroom organizers review your presentation slides or any other content for CoC compliance, please email us and we will do our best to assist you. Call for Volunteers ------------------- We are also looking for volunteers to help run the devroom. We need assistance watching time for the speakers, and helping with video for the devroom. Please contact devroom mailing list[2] for more information. Questions? ---------- If you have any questions about this devroom, please send your questions to our devroom mailing list. You can also subscribe to the list to receive updates about important dates, session announcements, and to connect with other attendees. See you all at FOSDEM!

[PATCH 0/7] Sanitize logic to get live/config device definitions for unplug/update
by Peter Krempa 05 Dec '22

05 Dec '22

Convert code *DomainUpdateDeviceFlags/*DomainDetachDeviceLiveAndConfig to avoid use of virDomainDeviceDefCopy. We have the original XML string from the user so it doesn't make sense to parse it and then copy it (whcih involves formatting and parsing back), when we can simply parse it twice, saving the extra formatting step.

[PATCH v3] qemu: Don't report spurious errors from vCPU tid validation on hotunplug timeout
by Peter Krempa 05 Dec '22

05 Dec '22

From: Shaleen Bathla <shaleen.bathla(a)oracle.com> Use of qemuDomainValidateVcpuInfo in the helpers for hotplug and unplug of vCPUs can lead to spurious errors reported such as: internal error: qemu didn't report thread id for vcpu 'XX'" The reason for this is that qemuDomainValidateVcpuInfo validates the state of all vCPUs against the expected state of vCPUs. If an unplug operation completed before libvirt was unable to process it yet the expected state could not reflect the current state. To avoid spurious errors the qemuDomainHotplugAddVcpu and qemuDomainRemoveVcpu functions are modified to do localized validation only for the vCPUs they actually modify. We also now ensure that the cgroups are modified before bailing out on error for any vCPUs which passed validation. Additionally in order for qemuDomainRemoveVcpuAlias to be able to find the unplugged vCPU we must ensure that qemuDomainRefreshVcpuInfo does not clear out the alias in case when the vCPU is no longer reported by qemu.

[PATCH 00/12] JSON monitor handling cleanups and spurious error bug fix
by Peter Krempa 02 Dec '22

02 Dec '22

First half introduces qemuMonitorJSONGetReply and uses it in our code base, second half introduces virJSONValueArrayToStringList, uses it to fix a bug and refactor the rest of the usage. Peter Krempa (12): qemu: monitor: Introduce qemuMonitorJSONGetReply, a better qemuMonitorJSONCheckReply qemu: monitor: Use qemuMonitorJSONGetReply for VIR_JSON_TYPE_OBJECT qemu: monitor: Use qemuMonitorJSONGetReply for VIR_JSON_TYPE_ARRAY qemu: monitor: Use qemuMonitorJSONGetReply when the value is extracted directly qemu: monitor: Unify and refactor 'PTY' case in qemuMonitorJSONAttachCharDev util: json: Split out array->strinlist conversion from virJSONValueObjectGetStringArray qemuAgentGetDisks: Don't use virJSONValueObjectGetStringArray for optional data qemuMonitorJSONGetCPUDefinitions: Rework lookup of 'unavailable-features' qemuMonitorJSONGetCPUDefinitions: Avoid double lookup of object qemu: monitor: Use qemuMonitorJSONGetReply in conjunction with virJSONValueArrayToStringList qemuAgentSSHGetAuthorizedKeys: Convert last use ofvirJSONValueObjectGetStringArray util: json: Remove unused virJSONValueObjectGetStringArray wrapper src/libvirt_private.syms | 2 +- src/qemu/qemu_agent.c | 13 ++- src/qemu/qemu_monitor_json.c | 189 +++++++++++++++-------------------- src/util/virjson.c | 44 +++----- src/util/virjson.h | 3 +- 5 files changed, 106 insertions(+), 145 deletions(-) -- 2.38.1

[PATCH] commandtest: Comply with FreeBSD poll()
by Michal Privoznik 01 Dec '22

01 Dec '22

In one of recent commits I've introduced a new test case to commandtest. In the test case I'm using poll() to wait for data on a pipe (the write end is passed to commandhelper). However, on FreeBSD the POLLIN semantic is a bit different: POLLIN Data other than high priority data may be read without blocking. Well, the pipe is non-blocking, so even if there's no data to be read the flag is set (and subsequent read() returns 0). On the other hand, POLLHUP is set too, BUT, if the commandhelper manages to write everything into the pipe and die right after we'd get both POLLIN and POLLHUP after the very first time poll() returns. That's very unfortunate, but okay - we can just check whether read() returned zero and break from the reading loop.

Release of libvirt-8.10.0
by Jiri Denemark 01 Dec '22

01 Dec '22

The 8.10.0 release of both libvirt and libvirt-python is tagged and signed tarballs and source RPMs are available at https://libvirt.org/sources/ https://libvirt.org/sources/python/ Thanks everybody who helped with this release by sending patches, reviewing, testing, or providing feedback. Your work is greatly appreciated. * New features * Tool for validating SEV firmware boot measurement of QEMU VMs The ``virt-qemu-sev-validate`` program will compare a reported SEV/SEV-ES domain launch measurement, to a computed launch measurement. This determines whether the domain has been tampered with during launch. * Support for SGX EPC (enclave page cache) Users can add a ``<memory model='sgx-epc'>`` device to lauch a VM with ``Intel Software Guard Extensions``. * Support migration of vTPM state of QEMU vms on shared storage Pass ``--migration`` option if appropriate in order for ``swtpm`` to properly migrate on shared storage. * Improvements * Mark close callback (un-)register API as high priority High priority APIs use a separate thread pool thus can help in eliminating problems with stuck VMs. Marking the close callback API as high priority allows ``virsh`` to properly connect to the daemon in case the normal priority workers are stuck allowing other high priority API usage. * Updated x86 CPU features The following features for the x86 platform were added: ``v-vmsave-vmload``, ``vgif``, ``avx512-vp2intersect``, ``avx512-fp16``, ``serialize``, ``tsx-ldtrk``, ``arch-lbr``, ``xfd``, ``intel-pt-lip``, ``avic``, ``sgx``, ``sgxlc``, ``sgx-exinfo``, ``sgx1``, ``sgx2``, ``sgx-debug``, ``sgx-mode64``, ``sgx-provisionkey``, ``sgx-tokenkey``, ``sgx-kss``, ``bus-lock-detect``, ``pks``, ``amx``. * Add support for ``hv-avic`` Hyper-V enlightenment ``qemu-6.2`` introduced support for the ``hv-avic`` enlightenment which allows to use Hyper-V SynIC with hardware APICv/AVIC enabled. * qemu: Run memory preallocation with numa-pinned threads Run the thread allocating memory in the proper NUMA node to reduce overhead. * RPM packaging changes - add optional dependancy of ``libvirt-daemon`` on ``libvirt-client`` The ``libvirt-guests.`` tool requires the ``virsh`` client to work properly, but we don't want to require the installation of the daemon if the tool is not used. - relax required ``python3-libvirt`` version for ``libvirt-client-qemu`` The ``virt-qemu-qmp-proxy`` tool requires python but doesn't strictly need the newest version. Remove the strict versioning requirement in order to prevent cyclic dependency when building. * Bug fixes * Skip initialization of ``cache`` capabilities if host doesn't support them Hypervisor drivers would fail to initialize on ``aarch64`` hosts with following error :: virStateInitialize:657 : Initialisation of cloud-hypervisor state driver failed: no error which prevented the startup of the daemon. * Allow incoming connections to guests on routed networks w/firewalld A change in handling of implicit rules in ``firewalld 1.0.0`` broke incomming connections to VMs when using ``routed`` network. This is fixed by adding a new ``libvirt-routed`` zone configured to once again allow incoming sessions to guests on routed networks. * Fix infinite loop in nodedev driver Certain udev entries might be of a size that makes libudev emit EINVAL which caused a busy loop burning CPU. Fix it by ignoring the return code. Enjoy. Jirka
